- Nominal current (A): Check with amp-meter.
- Pump parts and impeller: Check for possible wear.
Replace defective parts.
- Ball bearings: Check the shaft for noisy or heavy opera-
tion (turn the shaft by hand). Replace defective ball bear-
ings. A general overhaul of the pump is usally required in
case of defective ball bearings or poor motor function.
This work must be carried out by an authorized
service workshop.
- Cable entry: Make sure that the cable entry is watertight
and that the cables are not bent sharply and/or pinched.
Visual control at pump types with oil chamber (mod-
els without cooling jacket or model „U" with cooling
jacket and open cooling circuit):
Oil level and oil condition:
The condition of the mechanical seals can be visually
controlled as follows:
Put the pump in horizontal position, so that the screw of
the oil chamber is on top (for larger pumps: one of both oil
chamber screws).
Remove the screw and take out a small quantity of oil.
The oil becomes greyish white like milk if it contains water.
This may be the result of defective shaft seals.
In this case the condition of the shaft seals should be
checked by a HOMA Service shop.
The oil should be replaced after 3000 operating hours.
Oil type: degradable HOMA-ATOX. Used oil has to be
disposed according to the existing environmental rules
and regulations
Servicing Contract
For a regular expert execution of all necessary mainte-
nance and inspection we recommend the conclusion of a
servicing contract by our HOMA Service. Please contact
our HOMA customer service.
Return of pumps
If a pump has been used for a liquid which is injurious
to health or toxic, the pump will be classified as contami-
nated.
If HOMA is requested to service the pump, HOMA must
be contacted with details about the pumped liquid, etc.
before the pump is returned for service. Otherwise HOMA
can refuse to accept the pump for service (see attach-
ment).
Possible costs of returning the pump are paid by the cus-
tomer. However, any application for service (no matter to
whom it may be made) must include details about the
pumped liquid if the pump has been used for liquids which
are injurious to health or toxic.
